Narrative:

WX scattered to broken with runway in area. Cleared to takeoff runway 19 with canales 2 departure moyuta transition. The departure requires that you intercept the aur 169 degree radial after takeoff to canales or 9000 ft, whichever occurs first, then turn to an 080 degree heading to intercept the 169 degree radial on course. Tower cleared us for takeoff, we asked for the noise abatement climb (company procedure) but the tower did not respond. As soon as airborne we contacted departure and asked for runway heading to 4 DME. Controller cleared us to FL410 and told us to intercept the 140 degree radial of aur to 20 DME, then on course. I started the left turn planning not to go east of the 169 degree radial until 9000 ft for terrain clearance per the departure. During the turn TCASII picked up traffic at 1 O'clock approximately 10 mi. I tightened up the turn but still got RA advisory which we complied with. Controller complained that we did not get on the 140 degree radial. However, we could not get to the 140 degree radial quickly enough to avoid a conflict because: 1) the departure specifies that we stay on the 169 degree radial until reaching 9000 ft. 2) the procedure requiring us to request runway heading till 4 DME puts us further south at a high rate of speed even when the request is denied because of the time delay. I strongly believe that company should drop this noise abatement procedure. TCASII saved the day. As a crew I do not see any way we could have avoided the conflict. ATC should have used altitude to separate us from the traffic.

Title: HDG DEV. PERCEIVED TFC CONFLICT.

Narrative: WX SCATTERED TO BROKEN WITH RWY IN AREA. CLRED TO TKOF RWY 19 WITH CANALES 2 DEP MOYUTA TRANSITION. THE DEP REQUIRES THAT YOU INTERCEPT THE AUR 169 DEG RADIAL AFTER TKOF TO CANALES OR 9000 FT, WHICHEVER OCCURS FIRST, THEN TURN TO AN 080 DEG HDG TO INTERCEPT THE 169 DEG RADIAL ON COURSE. TWR CLRED US FOR TKOF, WE ASKED FOR THE NOISE ABATEMENT CLB (COMPANY PROC) BUT THE TWR DID NOT RESPOND. AS SOON AS AIRBORNE WE CONTACTED DEP AND ASKED FOR RWY HDG TO 4 DME. CTLR CLRED US TO FL410 AND TOLD US TO INTERCEPT THE 140 DEG RADIAL OF AUR TO 20 DME, THEN ON COURSE. I STARTED THE L TURN PLANNING NOT TO GO E OF THE 169 DEG RADIAL UNTIL 9000 FT FOR TERRAIN CLRNC PER THE DEP. DURING THE TURN TCASII PICKED UP TFC AT 1 O'CLOCK APPROX 10 MI. I TIGHTENED UP THE TURN BUT STILL GOT RA ADVISORY WHICH WE COMPLIED WITH. CTLR COMPLAINED THAT WE DID NOT GET ON THE 140 DEG RADIAL. HOWEVER, WE COULD NOT GET TO THE 140 DEG RADIAL QUICKLY ENOUGH TO AVOID A CONFLICT BECAUSE: 1) THE DEP SPECIFIES THAT WE STAY ON THE 169 DEG RADIAL UNTIL REACHING 9000 FT. 2) THE PROC REQUIRING US TO REQUEST RWY HDG TILL 4 DME PUTS US FURTHER S AT A HIGH RATE OF SPD EVEN WHEN THE REQUEST IS DENIED BECAUSE OF THE TIME DELAY. I STRONGLY BELIEVE THAT COMPANY SHOULD DROP THIS NOISE ABATEMENT PROC. TCASII SAVED THE DAY. AS A CREW I DO NOT SEE ANY WAY WE COULD HAVE AVOIDED THE CONFLICT. ATC SHOULD HAVE USED ALT TO SEPARATE US FROM THE TFC.
